The Argentina international’s superb form for the Nerazzurri this season has caught the eye of the La Liga champions, who see him as the long-term heir to Luis Suarez.
Diario Sport reports that the Catalan club will test Inter’s resolve with an offer of €70 million plus Arturo Vidal and Nelson Semedo.
However, Real Madrid are also understood to be eager to sign the 22-year-old, who has scored 16 goals for the Italians this season.
Manchester United and Manchester City have also been linked with a move for the striker, who is said to have a release clause of €111 million which is only valid between 1 and 15 July.
Barca hope to tempt the player to the Camp Nou with a €7m per year deal that would treble his current earnings.
Martinez currently has a contract until June 2023 in Milan and has struck up a fruitful partnership with Romelu Lukaku this season, his second campaign with the club since arriving from Racing Club in 2018 for €24m.
Barcelona are also keen on bringing in Valencia winger Ferran Torres, according to El Mundo Deportivo.
The 19-year-old has enjoyed an impressive campaign and his employers are eager to tie him down to a new contract, with Liverpool and Real Madrid also hovering.
